Ok I have all the test results but we, vet and I are still at a loss as to what's wrong with Tus. The vets's main concern is with her USG which is 1.020, which is too diluted. Her cholesterol and Alk Phos. are on the high side as well and I'm thinking maybe cushing's disease?

So any ideas or suggestions on what to look for or where to look would be appreciated, as I don't think the kidneys are the main issue, they are a factor but there is something else going on that needs to be addressed.

Right now we have her on Pepid AC, I have a script for Zantex liquid, if the pepid is not working. I think I'll try and track down some of the slippery elm bark. Also have her on Amitriptyline - 5mg in the evening to help with her appetite and hopefully her gnawing on her back legs, and I still give her the benazepril, but I might give it to her every other day, still debating that one.

Anyway back to the drawing board, as the vet still thinks it's a cancer that has not manifested itself. Maybe so, but this illness has been going on for almost a year now, seems kinda long for a cancer and no serious decline
